Does photosynthesis produce ATP? | Yahoo Answers
So we can summarize by saying that the photosynthetic plantstrap solar energy to form ATP and NADPH (Light Phase) and thenuse these as the energy source to make carbohydrates and otherbiomolecules from carbon dioxide and water (Dark Phase),simultaneously releasing oxygen in to the atmosphere. Thechemoheterotrophic animals reverse this process by using theoxygen to degrade the energy-rich organic products ofphotosynthesis to CO2 and water in order to generate ATP fortheir own synthesis of biomolecules.
Light Dependent Reactions
The reactants of cellular respiration are: Oxygen and Glucose (Sugar)
Electron Transport Chain
ATP (Adenosine Triphosphate) is one of the principal chemical compounds that living things use to store and release energy
ADP (Adenosine Diphosphate) is an important organic compound in metabolism and is essential to the flow of energy in cells
3 Phosphate groups
The _____ reaction of photosynthesis produces oxygen …
Now this brings us to the next part - how do we go from glucose to ATP? This is achieved through the process of "oxidation" - and this is carried out through a series of metabolic pathways. Complex chemical transformations in the cell occur in a series of separate reactions to form each pathway, and each reaction is catalyzed by a specific enzyme. Interestingly, metabolic pathways are similar in all organisms, from bacteria to humans. In eukaryotes (plants and animals) many of the metabolic pathways are compartmentalized, with certain reactions occurring in specific organelles. Basically, cells trap free energy released from the breakdown (metabolism) of glucose. This energy gets trapped in the ATP as it converts from ADP to ATP by the addition of phosphate.
A lot of my college students still have trouble with this one. The reactions that happen in respiration and photosynthesis are different, but if we just look at what goes in and what comes out, they're opposites.
Carbon dioxide (CO2) and Water (H20) in, Oxygen and Sugar out.
Requires energy from the sun.
Here's cellular respiration:
Oxygen and Sugar in, CO2 and H20 out. Releases energy from the sugar.
Plants can do both. When they have light, they use it as an energy source to put the pieces of CO2 and H2O to make sugar. They can put a bunch of sugars together to make starch (what foods are starchy?), cellulose (the stringy stuff you can't chew up), and wood.
When it's dark, they can do cellular respiration to break down the starch and sugar to release the energy they need.
Poor animals, we can only do cellular respiration. We need foods like starch, and oxygen, and we breathe out the CO2 that's made. We don't get enough water from the process to take care of all of our needs so we have to drink more. Kangaroo rats don't have to drink water. They conserve water a lot better than we do.

Thanks for asking.
reaction of photosynthesis produces oxygen and ATP
Cyclic photophosphorylation occurs less commonly in plants than noncyclic photophosphorylation, most likely occurring when there is too little NADP+ available. It is also seen in certain photosynthetic bacteria. Cyclic photophosphorylation involves only Photosystem I and generates ATP but not NADPH. As the electrons from the reaction center of Photosystem I are picked up by the electron transport chain, they are transported back to the reaction center chlorophyll. As the electrons are transported down the electron transport chain, some of the energy released is used to pump protons across the thylakoid membrane from the stroma of the chloroplast to the thylakoid interior space producing a proton gradient or . As the accumulating protons in the thylakoid interior space pass back across the thylakoid membrane to the stroma through ATP synthetase complexes, this energy is used to generate ATP from ADP and Pi (see Fig. 4).
The plant uses the largest molecules to construct cell walls as the plant grows larger.The following equation sums up the photosynthesis reaction:
Sunlight + 6H2O + 6CO2 → C6H12O6 + 6O2In words, this equation states that sunlight, combined with six molecules of water (H2O) and six molecules of carbon dioxide (CO2), produces one molecule of sugar (C6H12O6) and six molecules of oxygen gas (O2).Through this process, green plants capture energy from the sun, use some of it to function and grow, and store some of it in their plant structure, where it’s available to other organisms when they eat the plants.

How does photosynthesis produce oxygen?
Photosynthetic organisms can be divided into two classes:those which produce oxygen and those which do not. Photosyntheticbacteria do not produce oxygen (in fact some of them calledanaerobes cannot tolerate oxygen) and this is considered a moreprimitive type of photosynthesis (in which the hydrogen donor ishydrogen sulfide, lactate or other compounds, but not water).Plants and one type of bacteria (cyanobacteria) do produceoxygen, an evolutionarily more advanced type of photosynthesis(in which the hydrogen donor is water).
SC.912.L.18.9 Photosynthesis and Cellular Respiration
Photoaututrophs utilize sunlight for energy and CO2 for theircarbon source by this process of PHOTOSYNTHESIS whereby sunlightis absorbed by a complex compound known as chlorophyll andconverted to energy which drives a series of chemical reactionsthat ultimately removes hydrogen from water or other compoundsand then combines the hydrogen with carbon dioxide in a way thatproduces sugars.
You need to know how photosynthesis and cellular respiration ..
During oxygenic photosynthesis, light energy transfers electrons from water (H2O) to carbon dioxide (CO2), which produces carbohydrates. In this transfer, the CO2 is "reduced," or receives electrons, and the water becomes "oxidized," or loses electrons. Ultimately, oxygen is produced along with carbohydrates.
ATP, while photosynthesis releases ATP
There is also light-independent photosynthesis, which USES ATP and creates glucose from carbon dioxide and water, producing oxygen as a waste product. This is really an energy storage mechanism, so that the organism doing it can later burn the glucose through glycolysis and respiration. This also happens in chloroplasts, so plants can, and animals can't.
